Two emotional and graphic days of testimony led up to the jury's decision Thursday.

The girl testified Wednesday that she had been drinking alcohol and had spurned Keadle's advances at least five times that night. She said she had consensual sex with another man before falling asleep in a bedroom, but that she awoke to find Keadle having sex with her.

The charge of first-degree sexual assault of a minor carries a punishment of up to 50 years in prison. Sentencing is scheduled for April 24.

Testimony ended Wednesday without Keadle addressing the court. His attorney, Jeff Pickens, said Keadle acknowledged that he had wanted to have intercourse with the girl but that he was unable.

In an April 2011 videotaped interview with police that was shown during the trial, Keadle told an investigator about suffering from an erectile dysfunction.

"You're asking if I had sex with her," Keadle said to the investigator. "No, I couldn't."

Keadle originally denied knowing the girl, then told the investigator that he tried to have sex with the girl but that he didn't realize she was only 15.

"Was I going to try? Yeah," Keadle said. "Did I know she was 15? No."

A physician's assistant testified that in July 2008, Keadle was prescribed a testosterone replacement gel because his testosterone level was low.

Minutes after the verdict, Nebraska Attorney General Jon Bruning released a statement saying he was pleased with the jury's decision.

"(Keadle) clearly took advantage of this young, naïve girl. We hope today's verdict will ensure he is ultimately held accountable for what he has done and the state will be recommending the maximum sentence," Bruning said.

Keadle, originally from Swansea, S.C., remains a person of interest in the December 2010 disappearance of a Peru State College student, Tyler Thomas. No charges have been filed in that case.
